About: How coal is formed - Practically demonstration!
sir make also on World Geo really you innovative
i think ur bituminous coal is not pure coal..i think it is carbonaceous shale..
uncal eska,upuyug batao
Thank you for the video
how do you explane the coal veins out west 20 feet of cover and 200 feet of coal?
I think the shiny one is the bituminus coal
very intelligent .
Thank you......this helped a lot!
what is the difference between coal and grahite
I think the time frame given for the ages of coal is incorrect, actually much of the information here is based off of long held assumptions that are now being questioned. It takes a long time before other ideas are given even the slightest consideration.
very informative and well presented.
How to Lignite carbon percentage 60-70 as well as moisture 75% ! and in sub-bituminous carbon content 35-45 %? Please, upload the right information. You don't know about coal.
Very clear and helpful! Thanks!
how does the plant material become pure carbon? what happened to everything else? why doesn't peat decompose and lose its carbon when it's mostly burned off as CO2 by the bacteria? where do the hydrocarbons in bituminous coal come from? where do they go when the coal turns to anthracite?
Hi, first of all thank you for the video, i know nothing about coals and you have explained it really clear for me.
I want to ask you a few questions about identifying the coal type. I have recently come across in doing identification experiments of coals, I have a lab report of the sample coal content, but I am having trouble identifying which type of coal it is. So I am hoping you could help me out here.
The sample was tested in air dried basis, and the results are as follow: moisture 1.5%, ash 14.3%, Vol 17.4%, Fix carbon 67% and total sulfur 0.41%. It has a dark black color surface (unlike the gray color surface in your video), it has a bit of the shiny surface (not a lot), and it was pretty dense. At first I thought it was a bitumious coal, but then its carbon content was only 67% and it has a low moisture value. Base on the info, would you be able to identify which type it is? and perhaps explaining to me why it has such low carbon content and low moisture percentage please? Also is sulfur a big factor to coals? thank you!!
great vid, thanks! exactly what i was looking for! title should be 'practically shown' or 'practical demonstration' as 'showed' in this case is grammatically incorrect. Keep up the great work!
Very helpful video! Idk if it’s because I am in a general Earth Science course or what, but my professor said that anthrocite actually is the worst coal, because most of the carbon has been taken out of it. This happens because it sits too long. Bituminous is the best. Idk. Just relaying info. 😬😂
